4AGZE Swap Options

[mikecelica]

I've been planning on turboing my st for a while now, got all the parts, but after going through all the costs with parts and labor I've come to a total of $3100, which I think is waay too much for 40-50hp (If even that). I wouldnt be getting much horsepower, plus risk damaging the engine, and say goodbye to the toyota reliability. So Im thinking now of just swapping in a 4agze, Ive been reading up alot about this and what i wanna know is why people think its such a difficult swap and that only few people have attempted it? Ive gone through this with a mechanic at toyota dealership that I work at. And he too says its the most simplest of swaps. All i really need is the engine,ecu,wiring harness,4age flywheel with using my 7afe tranny and same motor mounts. Thats pretty much it, unless I put in FMIC, but I've heard they benefit more from TMIC. The 4agze from the Levin from has about 170hp at stock psi (7psi) and at full boost (14psi) it should reach around 190hp or more with some pulleys and an safc. Plus another advantage would be that this engine was built to handle boost so its alot more safe than a 7afte. This mechanic has a 88 corolla gts with the 4agze and an mr2 4agze and they are faast. So I just wanna hear some thoughts on this. thanks

Heres my .02...

Spend the money you'll be puting into your setup either way in the smartest of places....by purchasing the absolute cleanest 4AGZE clip that you can from a Levin.


Tear the Celica down and tear the clip down, and send out your harnesses to get the wiring done by Tweak since he has already done it in the past. With that out of the way, the most challenging part is out of the way. You can use all your current mounts, transmission, axles, starter, flywheel, just like you said....pretty straightfoward.
From there, all you would need would be a slightly higher duty fuel pump from an All-Trac/GT-Four or N/A 2JZ-GE Supra to make sure you don't run the motor short of fuel, and a FMIC or an aftermarket water to air unit. Keeping the top mounted cooler will soak in ALOT of heat if you keep it....and detonation isn't any fun.




4AGZE is a pretty viable option and it really isn't any more complicated than any other swap. I would say to go for it, without a doubt. 7AFE's and 4AFE's both have a tendancy to get leaky valve oil seals when they hit high mileage, and they have tiny little intake and exhaust runners too which are a limitation when you add boost to the picture. Plus the bottom end isn't nearly as robust on an un-opened 7AFE.

With the 4AGZE, you'll have a supercharged factory setup with a free flowing head with a strong bottom end that you won't ever have to worry about failing....for the same investment. If your power requirements ever change you can either upgrade pulleys, add a turbocharger and twin-charge it, or make it all turbo and beat the snot out of it without any worries.



Good luck.
